If you ask me, Friday was a red-letter day for San Diego. Just imagine if the overdue demise of the city’s red-light camera program were only the start of the end of numerous urban aggravations.

What would you want Mayor Bob Filner to end next?

It’s a question I posed to a range of San Diegans on social media Friday morning, after Filner evoked memories of Ronald Reagan by ordering a city employee to tear down the first of many photo-enforcement signs around town, then joked that the sign was headed to the Smithsonian Institution.

Hope you have pen and paper handy, Mr. Mayor. I have five ideas for you.

But first, a toast to our victory, San Diego. Those $490 tickets that never proved to reduce overall accidents but actually increased rear-end collisions? Buh-bye.

Since criticizing then-Mayor Jerry Sanders over red-light cameras on Oct. 31, I’ve been counting the days until city officials begin removing all “photo enforced” signs. It took just 93 days.

That’s fast by the slow standards of San Diego politics, where divisions have lasted decades over issues such as the Mount Soledad cross and the Children’s Pool seals in La Jolla. Then again, San Diego’s complaints with red-light cameras date back to the program’s inception in 1996 when — and this is rich — Sanders was police chief and oversaw its launch.

Partly because of that, I wrote in this space three months ago that Sanders’ legacy would be tainted by the controversial program if he stood by as the renewal of its contract moved ahead at City Hall.

The day that column ran, his office announced he would leave the program’s fate to one of the two men campaigning for his job, both of whom opposed it.

Friday, I asked Filner if his decision was as easy as I considered it.

“Nothing is a no-brainer,” he told me. “Look, every one of these issues has pros and cons. Some are more easy than others.”

Filner said he talked it over extensively with Police Chief William Lansdowne, bicyclists, pedestrians, the business community and tourists. In the end, he said, it seemed “the hostility” toward the cameras “bred more disrespect for the law than respect for it.”

Now respectfully, sir, here are those five ways you can put the “ban” in urban aggravation.

Since it would be self-serving to augment this list with Torrey Pines or Mission Center roads, two streets I travel frequently, let me suggest a few that pose problems for residents: University Avenue, Miramar Road and Mira Mesa Boulevard. Also, Torrey Pines and Mission Center roads!

2) Raze Pernicano’s restaurant.

Jan Rieger, another local public relations pro, wants Filner to demolish the long-shuttered Hillcrest pizzeria, which has been an eyesore for decades. You know, since he’s tearing things down and all.

Maybe Filner’s negotiating style would succeed where so many others have failed. Minority Chargers owner and majority pain in the neck George Pernicano has steadfastly refused to do little other than let his 25,000-square-foot building in a prime part of town sag into further disrepair.
